HAND STAMP.

Application filed October 13-, 1922.

a guard so constructed as to cause it to roll under the influence of gravity to a given position when placed upon a substantially horizontal surface. Another object 01 the invention is to provide a structure for this purpose which can be economically manufactured and which can be readily applied to existing forms of hand stamps.

Other objects of invention and features of novelty will be apparent from the following specification when taken in connection with the accompanying drawings in which Figs. 1 and 2 are a View in perspective anda plan view, respectively, of one form of the invention as applied to a dating stamp.

Figs. 3 and 41 are a view in perspective and a view in side elevation, respectively, of another form of the invention as applied to a dating stamp.

Fig. 5 is a View in perspective of one member shown in Figs. 3 and 4:.

Figs. 6 and 7 are a view in perspective and a view in side elevation, respectively, of

another form of the invention as applied to a dating stamp.

Fig. 8 is a view in perspective of one of the members shown in Figs. 6 and 7.

Fig. 9 is a view in perspective of another form of the invention as applied to a hand stamp of a type in common use. I

Figs. 10 and 11 are a view in perspective and a plan view, respectively, of another form of the invention, as applied to a hand stamp in common use; and

Fig. 12 is a side elevation showing another modified t'ormof the invention as applied to a hand stamp of the type shown in Figs. 9 to 11.

In the use of hand stamps it is frequently ditlicult to avoid printing with the type inverted, and the present invention insures that the stamp will always roll to a given Serial No. 594,275.

position, though carelessly placed or dropped, so that the user can pick it up and use it without havinghis attention distracted from his work. I

In Figs. 1 and 2, a dating stamp is shown having a top portion 11, with depending side pieces 12 depending therefrom and a lower cross piece 13. A handle 14 is secured to the center of the top portion 11 and the usual type bands 15 are stretched over the lower cross piece 13 and over wheels 16 which are mounted on a pin 17, supported at its ends in the side pieces 12. From the top portion '11, an integral arm 18 extends in a curve downwardly as shown and is terminated at a point ad jacent the printing face, and, from that I edge of the stamp which corresponds to the lower edge of the type, arms 19 and 19 integral with the side pieces 12, extend in a wide curve, as best shown in Fig. 2, to meet each other at the arm 18 on the other side of the stamp. If desired the arms 19 and 19 may be riveted, welded or-otherwise secured to each other and to the arm 18 at the point 20. It will also be apparent that, if desired, the arms 19 and 19 may take the form of a loop integral with the frame portions 11 and 12 and bent back to the position in which the arms 19 and 19 are shown.

When the stamp is placed upon a substantially horizontal surface, it will be supported on one of the lower corners of a side piece 12 and one of the curved arms 18, 19 or 19 or upon the handle 14 and one of the curved arms 19 or 19 lneither case the center of gravity of the device as a whole is such that it is in unstable equiand with an extension 18 provided with an opening 18 to receive the pin upon which the handle 141 is secured. A curved arm 19 is reversely bent to provide end-portions 19 which are formed with openings 19 so that it can be mounted upon the pintl' 'l' as shown. It will be apparent that the end portions 19 may be mounted either outside of the side pieces 12, as"'sh'own-, or inside-suchside"- pieces, and that, if desired, a bolt may be The arm 19 substituted for the pin 17. may be welded, riveted onotherwise secured to the arm 18 at the point 20; and the extension fll8amaybe, dispensed-with if the. arms are rigidly secured each other;
